Definitions

  • the invention relates to a reinforcing structural material made of a plurality of fiber assembly cords, each cord comprising plural fibers, and the cords being formed into a braid characterized in that the braid is impregnated with a bonding agent.
  • the invention further relates to a reinforced fibrous inorganic structure characterized by comprising a molded inorganic composite, short fibers mixed therein, and at least one reinforcing structural material embedded therein, the reinforcing structural material being in the form of a braid comprising a plurality of fiber assembly cords and impregnated with a bonding agent.
  • This invention relates to a reinforcing structural material used in place of a reinforcing steel bar, a PC steel wire or the like for reinforcing the tensile strength of a structure or building by being embedded in a main structural material such as concrete, plastic or the like which is weak in tensile strength.
  • Reinforcing steel bars have previously been known as a reinforcing structural material, but these steel bars are inconvenient in that the bending work and bar arrangement work thereof are difficult, resulting in lowered workability thereof and in increase in weight of a structure.
  • the applicant of this application in Japanese Patent Application No. Sho 58-224410 has proposed a reinforcing structural material braided with a plurality of fiber assembly cords, each comprising plural fibers.
  • This proposed reinforcing structural material is not sufficiently strong because the plural fiber assembly cords are not bonded with each other and, in addition, the plurality of individual fibers constituting each fiber assembly cord are not bonded with each other.
  • a stress applied to each cord or fiber is not transmitted to the whole of the reinforcing structural material.
  • the tensile strength of the reinforcing structural material is insufficient because a stress applied thereto is transmitted through the mutual friction between the cords or fibers.
  • a purpose of this invention is to provide a reinforcing structural material free from the foregoing conventional problems and to provide a type of reinforcing structural material wherein a plurality of fiber assembly cords, each comprising plural fibers, are formed into a fibrous braid and the braid is characterized by impregnation with a bonding agent.
  • Another purpose of this invention is to provide a reinforced fibrous inorganic structure excellent in toughness, tensile strength, light in weight and characterized by comprising a molded inorganic composite, short fibers mixed therein and at least one reinforcing structural material embedded therein, the reinforcing material being in the form of a braid comprising a plurality of fiber assembly cords and impregnated with a bonding agent.
  • FIG. 1 is an enlarged front view of part of one exemplified reinforcing structural material of this invention.
  • FIG. 2 is a perspective view of part of one exemplified reinforced fibrous inorganic structure of this invention.
  • the reinforcing structural material 1 is constructed such that, for example, eight fiber assembly cords 3, each comprising a plurality of fibers 2 made of aromatic polyamide fibers, are interwoven into a braid 4.
  • the braid 4 is impregnated with a bonding agent 5 so that the bonding agent 5 may bond not only the cords 3 together, but may also bond together the fibers 2 of each cord 3.
  • the aromatic polyamide fibers constituting the fibers 2 may contain fibers of straight coordinated aromatic polyamide, aromatic polyether amide, aromatic polysulphide amide, aromatic polysulphone amide, aromatic polymethylene amide, aromatic polyketone amide, aromatic polyamine amide and copolymers thereof, etc.
  • the fibers 2 are not limited in kind to the foregoing aromatic polyamides, and instead thereof the fibers may comprise carbon fibers, glass fibers, ceramic fibers or other desired inorganic fibers; polyester fibers, strong aliphatic polyamide fibers, high strength polyolefin fibers, strong polyvinylalcohol fibers or any other desired organic fibers; or cold drawn steel wire, steel wire for prestress or any other desired metallic fibers; in a single or combined use selected from the above desired kinds of fibers.
  • the fiber 2 can take a variety of cross-sectional shapes along the longitudinal length thereof. But if the fiber 2 is formed so as to have different cross sectional shapes along its longitudinal length, then this configuration will increase the frictional force between the individual fibers and, as a result, stress applied to each fiber can more easily be transmitted to the entire reinforcing material 1. In this situation in a product where the reinforcing material 1 is embedded in an inorganic composite 6 as shown in FIG. 2, a close contact between the reinforcing structural material 1 and the inorganic composite 6 can be improved, resulting in an improved structural product.
  • the diameter of the fiber 2 to be used is generally in the range of from several microns to several tens of microns.
  • the cords 3 may be interwoven into a flat braid, a square braid or any other desired shape.
  • the braid 3 may also be formed into a braid which is different in its sectional shape along the longitudinal direction thereof to improve the close contact between the same and the inorganic composite 6.
  • the bonding agent 5 may be comprised of, for example, a cold setting or thermosetting resin such as of the epoxy type, polyester type, vinylester type, phenolic type, polyimide type, etc.; a cold setting or thermosetting inorganic bonding agent such as of the alkali metal silicate type, colloidal silica type, or phosphate type; or a mixture of a cold setting or thermosetting organic resin and an inorganic bonding agent.
  • An impregnation ratio of the bonding agent to the braid may be 10-50 parts by weight, preferably 30-40 parts by weight of the former to 100 parts by weight of the later.
  • the fibers 2 of the braid 4 are bonded one with another with the bonding agent 5 by following a process such as a process wherein after the fiber assembly cords 3 are braided, the braid is immersed in an uncured bonding agent in a liquid form so that the fibers 2 of each of the fiber assembly cords 3 may be impregnated with the liquid bonding agent and thereafter, the braid is subjected to a curing treatment or a process such that each fiber assembly cord 3 is impregnated with the liquid bonding agent 5 and, subsequently, a plurality of fiber assembly cords are braided together to form the braid.
  • the bonding agent 5 is then subjected to a curing treatment.
  • the reinforcing structural material 1 may be produced in the form of a straight material or in the form of any desired curve shape.
  • the reinforcing structural material 1 may be produced not only at a factory, but also at the site of construction of a building, for instance.
  • the reinforcing structural material 1 is used as a reinforcing member, such as a shearing reinforcing bar which is usually required to be bent, for instance, or a coiling round main reinforcing bar in the case of a bar arrangement work
  • the reinforcing structural material 1 is coiled around the main reinforcing bars while the bonding agent 5 impregnated therein is not yet completely cured, whereby the bar arrangement work can be performed firmly and reliably.
  • the integrity of the inorganic composite 6 can be improved by coating a film, such as hydrophilic material of a wettable and underwater settable type epoxy resin or the like, on the peripheral surface of the reinforcing structural material 1.
  • the reinforcing structural material 1 of the braid-type may also be used as is or in a net or fabric form obtained by interweaving a plurality of braids.
  • FIG. 2 shows one exemplified reinforced fibrous inorganic structure of this invention comprising a molded inorganic composite 6 formed into a hollow square tubular body, short fibers 7 uniformly mixed therein and the eight reinforcing structure materials 1 in the form of a round braid embedded therein at regular intervals therebetween in the peripheral direction thereof and in parallel along the longitudinal direction thereof.
  • the inorganic composite 6 comprises, in general, cement, sand and water. Instead of cement, however, plaster may be used, as the main component of said composite.
  • cement any kind of cement may be used selected from Portland cement, aluminous cement, Portland blast-furnace cement, silica cement, flyash cement, etc.
  • milling aids retarders, accelerators, water reducing agents, coagulants, thickeners, builders such as an air entraining agents, etc., and suitable-sized aggregates.
  • Short fibers 7 are mixed into the composite for improving toughness of the reinforced fibrous inorganic structure.
  • Short fibers 7 may be comprised of one or more of the various fibers as enumerated above for the fibers 2.
  • the short fibers 7 should range in size from several microns to several tens microns in diameter and from 5 to 15 mm in length.
  • Those fibers are preferably mixed in the inorganic composite in an amount of up to 2% by volume relative to the inorganic composite.
  • the content ratio of the reinforcing structural material 1 5% by volume thereof at the maximum is, in general, contained therein.
  • the inorganic composite including the short fibers and such disposed reinforcing structural materials was extruded under a vacuum of 75 mm Hg under an extrusion pressure of 10 kg/cm 2 and at an extruding speed of 1.5 m/min., so that there was formed an extruded mold body, i.e., a reinforced fibrous inorganic structure having a rectangular sectional shape of 50 mm by 100 mm.
  • the reinforced fibrous inorganic structure was cured for 14 days at 20° C., so that there was produced a molded reinforced fibrous inorganic structure.
  • the bending strength thereof was 205 kg/cm 2 .
  • the reinforcing structure material of a braid type is impregnated with a bonding agent, so that the respective mutual bondings between the fiber assembly cord can be performed. Accordingly a stress applied to each of the fibers can be transmitted to the whole of the reinforcing structural material reliably without fail, and a tensile strength of the reinforcing structural material is excellent.
  • the reinforced fibrous inorganic structure comprises a molded inorganic composite, short fibers mixed therein and at least one foregoing reinforcing structural material of this invention embedded therein, so that the product is excellent in toughness and is light in weight.
